I want to achieve following query in elasticsearch.  
select max(creationDate - updatedDate) from sudentTable;

how to write above query?

elasticsearch verison is v1.1.1

select max(creationDate) from sudentTable; is writtren like below

public static void max() {  
final searchRequestBuilder builder = getClient().prepareSearch("indexname").  
setTypes("type1");  
MaxBuilder mx = AggregationBuilders.max("maxDate");  
mx.field("creationDate");  
builder.addAggregation(mx);  
System.out.print("builders:::"+builder);  
Aggregations ag = builder.execute().actionGet().getAggregations();  
InternalMax inMx = ag.get("maxDate");  
System.out.print("aggg::"+inMx.getValue()+"\n");  
}
